*A Few Hours Back*
Nadia's fingers flew across the keyboard with a urgency, her eyes darting between the multiple screens grid-lined with security camera feeds. She was desperate to find any hint, any clue, any shred of evidence that might explain Tyler's sudden and inexplicable vanishing act. Her mind raced with worst-case scenarios, her heart pounding in her chest. "Calm down and search," she whispered to herself, trying to steady her racing thoughts. "He can't have gone far, and he certainly didn't disappear into thin air."
With a deep breath, she refocused her attention on the screens, her eyes scanning the footage with a newfound intensity. She rewound the tapes, fast-forwarded, and paused, scrutinizing every frame. She checked the cameras outside, the corridors, the elevators, and the stairwells. Nothing. It was as if Tyler had never existed.
